I enjoyed every bit of my swimming career. I think that's the most important advice - to enjoy what you do

When I was training for the Olympics, I didn't eat the way I should have. I missed out on much-needed protein and opted for every easy carb.

I've been barefoot most of my life: either flip flops or barefoot on the pool deck. Although you'd think that would make me a good candidate for barefoot running, that doesn't work with me.

You can't go wrong with some nuts. The key word is 'some.' Eat them one at a time, not by the handful.

I lead by example. My kids know what sweat is. They've seen me come home from so many runs and asked, 'What's on your skin? How did you get it?' And I tell them, 'It's from exercise!' So now my son will come home from a bike ride, take off his helmet and say, 'Look, Mom. I'm sweating! I just worked out!'

I have so much to learn when it comes to running. I just don't ever want it to feel like a chore. When I choose to sign up for a race or go out for a run, it's to make myself feel good, and I almost always do.

The kids know what I'm doing when I exercise, and that's powerful. So don't just tell your kids to go play outside. Take a moment off your computer, put on your tennis shoes, hop outside and help them start their game and run off some energy.
